In conclusion, the present study indicated that endovascular treatment is a safe and efficient method for patients with vertebral artery aneurysm. The treatment strategy should be based on the patient's condition and aneurysmal characteristics. Parent artery occlusion may be suitable for selected patients with ruptured vertebral artery aneurysms. PMID: 31798709 [PubMed]
ABSTRACT Aneurysmal subarachnoid hemorrhage is a condition with a considerable incidence variation worldwide. In Brazil, the exact epidemiology of aneurysmal SAH is unknown. The most common presenting symptom is headache, usually described as the worst headache ever felt. Head computed tomography, when performed within six hours of the ictus, has a sensitivity of nearly 100%. It is important to classify the hemorrhage based on clinical and imaging features as a way to standardize communication. Classification also has prognostic value. In order to prevent rebleeding, there still is controversy regarding the ideal blood pre...
CONCLUSIONS: The short-term angiographic findings showed that T-stent-assisted coiling is a feasible and effective endovascular method to treat wide-necked complex bifurcation aneurysms. The long-term angiographic follow-up results suggest that T-stent-assisted coiling provides a durable treatment for wide-necked complex bifurcation aneurysms with favorable clinical outcomes, demonstrating the long-term safety of T-stent-assisted coiling.

CONCLUSIONS: RAE is safe and effective for the management of iatrogenic IRVI showing high technical and clinical success rate and low complication rate. ADVANCES IN KNOWLEDGE: Low pre-procedural hemoglobin levels increase procedural duration time. Glue alone or in combination with other materials is as safe as coils.

Introduction: Arterial injuries can occur in a vast array of arterial beds with substantial morbidity and mortality. Endovascular therapy (embolization/covered stent) provides a minimally invasive and effective alternative to surgery. The endovascular technique depends on the type of the vessel and the injury location, since embolization with coils, plugs or liquid embolic agents or implantation of covered stents can be performed. In particular stentgrafts allow the exclusion of the lesio/defect without the sacrifice of the target vessel avoiding ischemic complications.
This study sought to assess the morphologic characteristics of ICAs and the effects of tortuosity on thrombectomy attempts. METHODS: A retrospective review was completed of neck CTAs of patients with acute ischemic stroke due to a large vessel occlusion that underwent attempted endovascular recanalization. Significant tortuosity of ICAs was defined as the presence of kink(s) (acute (
In this work, an injectable and radiopaque liquid metal/calcium alginate hydrogel is fabricated for endovascular embolization and tumor embolotherapy. Such hydrogel has flexibility and radiopacity due to adoption of liquid metal droplets. It also owns excellent biocompatibility and hemocompatibility to facilitate future clinical applications. Rather promising therapeutic effects are achieved by conceptual experiments on this hydrogel for tumor embolotherapy. AbstractImproved endovascular embolization can contribute to assistant treatment for patients. However, many traditional embolic materials, such as metal microcoils or...
ConclusionsTemporary arterial flow redistribution using a retrievable coil was feasible in the healthy pig model and could be applicable for endovascular procedures in which superselection is difficult or unavailable.
J Neurol Surg A Cent Eur Neurosurg DOI: 10.1055/s-0039-1685513 Objective Intracranial aneurysms treated with endovascular coil embolization may recur. We investigated the factors affecting aneurysmal recurrence after embolization and effects of endovascular retreatment within 1 year. Methods In 3 years, 1335 patients with 1385 intracranial aneurysms were treated with coil embolization. Factors affecting aneurysm recurrence and the effects of endovascular retreatment were analyzed. Results Angiography immediately following embolization showed total occlusion in 1030 aneurysms (74.4%), neck remnant in...
